SLiM simulation script moderate SOD M3

Forward simulation script for the scenario: moderate symmetrical overdominance, selection strength s = 0.05, migration M3 = 2.36E-06. Script run in SLiM v2.5. Example command to run the script: "./slim -d simnum=00000 -d u=1.17e-7 -d locus=0 example_simulation_6_pops_00000_0.txt". example_simulation_6_pops_00000_0.txt - name of the SLiM script with one simulation specification; simnum - simulation number; u - locus mutation rate; locus - locus number.针对中度对称超显性（moderate symmetrical overdominance）场景的正向模拟脚本：选择强度s=0.05，迁移参数M3=2.36×10^-6。本脚本基于SLiM v2.5运行。示例运行命令为："./slim -d simnum=00000 -d u=1.17×10^-7 -d locus=0 example_simulation_6_pops_00000_0.txt"。其中，example_simulation_6_pops_00000_0.txt为包含单次模拟配置的SLiM脚本文件名；simnum为模拟编号；u为位点突变率；locus为位点序号。
